Do Not Disturb sync across devices disrupted by VPN
I realized that using VPN (IVPN) on my Mac Mini (M1) shuts out ability to sync Do Not Disturb (DND) with my iPhone 15Pro, Apple Watch 6, and MacBook Pro (2022 M2) (all operating systems up-to-date as of today, October 25, 2024). To test this, I turned off the Mini's VPN and turned on DND, which synced across devices; then I turned VPN back on and then turned off DND, which did not sync across the devices.
Anyone find a way to bypass this VPN effect on DND?
TIA.
Mac mini, macOS 15.0
